oAR-AxLE Box.

SPECIFICATION forming part of Letters Patent No. 657,744, dated September 11, 1900.

Application filed July 2l., 1900. Serial No. 24,409. (No model.)

To @ZZ whom, it may concern:

Be it known that I, THOMAS J. MORGAN, a citizen of the United States, residing at Kingston, in the county of Luzerne and State of Pennsylvania,bave invented certain new and usefulImprovementsin Oar-Axle Boxes; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to axle-boxes for cars or trucks used on mining-railroads and other places; and it consists in the novel construction and combination of the parts hereinafter lfully described and claimed.

ln the drawings, Figure l is a sectional View of a portion of a car provided with an axle-box according to this invention. Fig. 2 is lan end view of the axle-box drawn to a larger scale. Y

A is a portion of the car or truck frame.

B is a portion of a car-axle, and C is one of the car-wheels.

The axle -box is formed of two partsnamely, a bracket D and a bearing-block E. The bracket D is secured to the car-frame by bolts l) and is provided with a forked guide d at its lower part, having inwardly-projecting lugs (Z, which form a stop at its lower end. The bracket is also provided with a lug c, which projects from the upper part of the side which is farthest from the car-wheel. The bearing-block E engages loosely with the forked guide d and is prevented from dropping ou t of it when the car-b0dy is raised by means of the lugs CZ', which only permit the bearing-block to be separated from the bracket to a limited extent. The bearingblock E has an annular projectionfon one side, which engages with a socket f' formed in the hub of the car-wheel, so that no dirt can get into the bearing on the side next to the car-wheel. The axle is journaled in the bearing-block and in the projection f.

F is a chamber for oil and Waste or other approved lubricating material. This chamber is formed in the bearing-block E at the end of the car-axle, and it has an opening at its top which is normally closed by the bracket D,'so that n0 dirt can get through it into the bearing.

G is a wedge-shaped projection on the end of the bearing-block under the lug c on the bracket. This projection is arranged with its apex uppermost, and I-I is a split pin which is driven through a hole in the lng c onto tbc projection G. The projection spreads the split pin and prevents it from rising. The split pin prevents the bearingblock from sliding endwise in the bracket and permits the bracket to be raised to lill the chamber F with oil. Flangcs 7L are also formed on the bearing-block and bear against the bracket D. These lianges assist in holding the bearing-blockand axle in position.

This axle-box forms a cheap and etlicient bearing for the axles of mining-trucks which work in much dirt, which requires to be kept out of their axle-bearings.

What I claim is l. In an axle-box, the combination, with a bracket having a forked guide, of a bearing block movable vertically in the said guide and having a chamber for lubricant which is normally closed by the said bracket, and having also a wedge-shaped projection at one end, and a split pin engaging with the said bracket and projection and preventing` the bearing-block from sliding endwise out of the bracket, substantially as set forth.

2. In antaxlebox, the combination, with a bracket having a forked guide provided with a stop at its lower parl, of a bearingblock which is'slidable vertically to a limited extent in the saidA guide, said block being provided with achamber for lubricant which is normally closed by the said bracket, and means for preventing the bearing-block from sliding endwise out of the bracket, substantially as set forth.4

3. In an axle-box, the combination, with a bracket having a forked guide, of a bearing-block having a chamber for lubricant near one end which is normally closed by the said bracket, and an annular projection at the other end for engaging with a recess in the adjacent car-Wheel, substantially as set forth.

4. In an axle-box, the combination, with a bracket having a forked guide and a pro- IOO by the said bracket, said block having also fianges which prevent it from sliding endwise in one direction and a Wedge-shape projection arranged under-the saidlug, and

a split pin passed through a hole in the said lug and engaging with the said projection and preventing the said block from sliding zo endwise in the other direction, substantially as set forth.

In testimony whereof I ax my signature' in presence of two Witnesses.
